例如，有下面一个数组

1. byte[] b ={1,2,3,4,0,7,9,0,0，0，0,0,0,0,0,0,0,0,0,1,0,0,0,0,0,0,0,0,1,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0};

复制代码

如何去除这个数组里的最后的那一串0，也就是去除数组中从某一位置开始一直到结尾都是0的串，上面的例子还稍微简单一点，如果数组很大，求实现！

package com.ttc;

public class test8 {

        int j ;
        public static void main(String[] args) {
                // TODO Auto-generated method stub
                test8 tt = new test8();
                int last = 0;
                byte[] b ={1,2,3,4,0,7,9,0,0,0,0,0,0,0,0,0,0,0,0,1,0,0,
                                0,0,0,0,0,0,1,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,
                                0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0};
                last = tt.LastArrays(b);
                //System.out.println(last);
                for(int i=0;i<=last;i++){
                        System.out.println("b["+i+"] ="+b[i]);
                }
        }
       
        public int LastArrays(byte[] b){
       
                //System.out.println(b.length);
                for(int i=b.length-1;i>=0;i--){
                        if(b[i]!=0){
                                j = i;
                                break;
                        }
                }
                return j;
        }
}

谢谢了！！
